WaveCast 724 Cast Coil
Description
Proven technology, application flexibility, lower installation cost,
operating efficiency and environmental acceptability are
hallmarks of the new GE WaveCast 724™ Cast Coil
Transformer. WaveCast 724's are designed for indoor or
outdoor applications in the most demanding and diverse
environments. Advanced design of the winding assembly
establishes superior performance to meet exacting customer
needs.
Features and Benefits
•
•
•
•
•
•
•
•
•
Mechanical strength: Because of the strong protection provided by the vacuum cast
epoxy insulated coils GE WaveCast 724 Transformers are mechanically stronger than
either liquid or ventilated dry type transformers.
Impervious to adverse atmospheric conditions: WaveCast 724 Transformers are
optimal for application in low quality environments. The epoxy casting is extremely
inert and renders the windings impervious to moisture, dirt and most corrosive
elements.
Suitability for simple Indoor Installations: Unlike the liquid filled transformers
indoor installations do not require an automatic fire extinguishing system or fire vault,
oil checking or replacing, or a liquid confinement area.
Extended ratings: WaveCast 724 Transformers can be provided with the highest
self-cooled and fan cooled extended ratings of any transformer in their size class.
Solid vacuum cast coils- provide optimum performance over a wide range of
ambient and operating temperatures.
High Voltage Windings- are vacuum cast with high-strength and essentially voidfree assembly capable of withstanding high electrical stress. Windings use Dupont
Nomex® layer insulation.
Low Voltage Windings- vacuum cast and hermetically sealed, windings use strip foil
helical form and Dupont Nomex® layer insulation.
Cores- utilize mitered step-lap technology ensuring optimal performance and minimal
sound levels.
Enclosures- indoor and outdoor construction. Options include aluminum and
stainless Enclosures, NEMA 12, drip-proof roofs.
